7 Steps to Changing Carrier Gas from Helium to Hydrogen

26 April 2016

Nitrogen, hydrogen, and helium are the most widely used gases by today’s chromatographer and each has unique benefits as well as drawbacks. Hydrogen has several features, such as higher optimal linear velocity, and flatter Golay curve, that result in decreased analysis times when compared to other GC carrier gas choices, but there can be some concerns about safety. From system set-up to consumables and optimizing analytical performance, this guide from Peak Scientific explains everything you need to know if you're changing from helium carrier gas to hydrogen.
